It is much more commonly a complication of UC though it can be seen occasionally in CD. The colon becomes paralyzed which can lead to it eventually bursting; this is known as a “perforation”.

Anyone with UC or CD serious enough to be at risk for toxic megacolon should be hospitalized and closely monitored. Warning signs include abdominal pain/tenderness, abdominal distention, fever, large numbers of stools with obvious blood and a rapid (more than 100/minute) pulse rate.
